[PATCH-for-9.0] docs: Deprecate the pseries-2.12 machines

Posted by Philippe Mathieu-Daudé 8 months, 2 weeks ago

pSeries machines before 3.0 have complex migration back
compatibility code we'd like to get ride of. The last
one is 2.12, which is 6 years old. We just deprecated up
to the 2.11 machine in commit 1392617d35 ("spapr: Tag
pseries-2.1 - 2.11 machines as deprecated").
Take to opportunity to also deprecate the 2.12 machines.

In 2025 I'd like to get ride of the code related to:

  include/hw/ppc/spapr_cpu_core.h:31:    bool pre_3_0_migration; /* older machine don't know about SpaprCpuState */

I can merge this via the PPC tree.

Thanks,
